I think Kerrigor meant that requiring politicians retire at the age of retirement would cause a push for retirement age to get bumped higher, and that it would be better for the maximum age for a politician to be tied to the average life expectancy (e.g. no more than 10 years younger than the average life expectancy, or some such).
I think that's the point. If you looked at a headline for something you already know about, then you already know if it bogus or not. If you already know how reliable the source is, then your exposure to risk of accepting bad information is reduced. The point is to see if you are susceptible to new information that is bogus, and if you can recognize when a source you haven't seen before is unreliable.
For those of us who understand how the platform works, it wouldn't be an issue. However, if we want mass adoption of the platform, we need to take into consideration those who don't fully understand the technology and avoid situations that will lead to scams where feasible. Names of authority, like admin, root, super, etc., make a user appear to have authority they don't, which can mislead new users. ("Support our server by sending bitcoin to this address that is really my personal wallet" type scams comes to mind.) You could say that it's the person's fault for falling for it, but it's something that would drive people away from the platform which can be easily avoided in the first place.
